Lemma 17.31.3. Let f : X \to Y be a continuous map of topological spaces. Let \mathcal{A} \to \mathcal{B} be a homomorphism of sheaves of rings on Y. Then f^{-1}\mathop{N\! L}\nolimits _{\mathcal{B}/\mathcal{A}} = \mathop{N\! L}\nolimits _{f^{-1}\mathcal{B}/f^{-1}\mathcal{A}}.
Proof. Omitted. Hint: Use Lemma 17.28.6. \square
